Specification of To allwhom it ma yponcem:

' Be it known that I, JAMES A. Glass, acitizen of the Unite'l'States,and resident of Chicago, county of Cook, and State of Illinois, haveinvented certain new and useful Improvements" in Doors, of which thefollowing is a specification, and which are illustrated in theaccompanying drawings, forming a part thereotl I l v The inventionrelates to doors having the latch casing housed within them, andbedoors.

In the manufacture of metal doors, such as-are now in quite common usein railway cars and other situations, it has been found difficult topermanently and satisfactorily secure the latch casing within thechamber of the door. The more common expedient of fitting within thedoor a mortised block to which the face plate of the latch casing hasbeen attached, has been attended with serious d'itficulties in practice,due to the tendency of the attaching screws to work 1oose,the inabilityto relieve the latch-controlling spindle of thed'uty of maintaining thelatch in place, and for other reasons.

casing to the side walls of the door; and the invention consists inadevice as hereinafter described and as illustrated in various forms inthe drawings, in which.

may be provided with the usual face plate" 14: and,-if desired, screwedto a supporting plate 15 attached to the inner 'face of the wall 12and-m'crlapping its opening. An escutcheon plate 16 applied to the outerface of one of the walls, as '11. of the door, and is prorided with aplurality ofstuds, as 17. 18 and 19, which project through this wall.The latch casing 13 is provided 'with a lug, here shown at 20,projecting from the inner end of the casing andengaging the end of thestud 17, to which it is secured by a screw 21, its face plate 14 beingheld The" wall 10 of the door is apertured, as shown' snugly against theseating plate 15.

which are in alinementand telescopic engagement. with the, studs 18, 19.Screws,

as :26, set through the escutcheon plate 23, enter threaded socketsin-the studs 18, 19,-

and drawthe two cscutcheon plates toward each other. The threadedsockets of the studs 18, 19, are of suiiicient depth to permit thescrews to be set up so as to slightly compress the plates 10. 11, of thedoor, whereby these plates by their elasticity serve to securely holdthe screws against turning under the influence of jars and vibrations.The latch-controlling spindle :27 may be of any desired form and pa...through the escutcheon plates 16 and '23. The latch is, however,securely held in position by the means described, so that the spindle is.not called upon to maintain it in position, and it is therefore free toturn in its bearings.

In the construction illustrated in Fig. 4, both of the escuteheonplates, here designated by the numerals 28, :29, are provided withinstanding' studs for attachment to the lug 20 ot the latch casing. Inthis stance the securing means is a screw 32 set through one of theescutcheon plates. as 29, through its stud 31, the lug 20, and into thestud fit). with which it iria-kes threaded engagement. 5y making thestuds30 and 31 of such length that they dd not normally reach the lug20, the plates l0, 11, may be slightly com1n'csscd for the purpose ofsecuring the proper spring action for preventing 'the screw from workingloose. When this form of constmcthtnis followed, it becomes unnecessaryto provide the aperture, as 22,

which cooperate with the studs 35, 36, of the cscutcheon plate insecuring the two escutdieon plates together. s uctimi ","lustrcted inFigs. and 6, the latch casing, here desi noted 37, is provided with aplnraiity oflugs, as 38, 39 and 4:0, each having a threaded aperture forreceiving screws, as all, 4172, 4.3, set directly through the side walls10, 11,01": the door, and tending to draw them up with a compressiveaction while securely holding the latch casing in place.
